PULVEBIZER.

Specification of Letters Patent.

Patented June 20, 1916.

Application filed August 31, 19141. Serial No. 859,542.

To (ZZZ whom it may concern:

Be it known that I, BYRAM W. STEELE, a citizen of the United States, andresident of \Vinterset, in the county of Madison and State of Iowa, haveinvented a certain new and useful Pulverizer, of which the following isa specification.

The object of my invention is to provide a pulverizer of simple, durableand inexpensive construction, so built and arranged as to break up thelarger clods or chunks of dirt into fine particles, and to break andsmooth the ground and to then arrange the ground in narrow, parallelridges.

My invention consists in certain details, in the construction,combination and arrangement of the various parts of the device, wherebythe objects contemplated are attained, as hereinafter more fully setforth, pointed out in my claims, and illustrated in the accompanyingdrawings, in which:

Figure 1 shows a perspective View of a pulverizer embodying myinvention. Fig. 2 shows a detail, sectional view of the same, taken onthe line 22 of Fig. 1, and Fig. 3 shows a side elevation of thepulverizer in its inverted position.

In the accompanying drawing, I have used the reference numeral 10 toindicate heavy planks of which I preferably use three. The planks 10 arearranged transversely in the machine with their front edges tiltedupwardly, as shown in the drawing. The front edge of the second andthird planks rests on the upper surface of the first and second planksnear their rear edges, as shown. For securing the planks together andgiving the device proper rigidity, I have mounted above the planks anangle iron 11, the forward portion of which is substantially horizontal,and. the rear end of which is inclined downwardly from a point at theforward edge of the rear plank 1.0, at 12. One angle of each angle iron11 is secured to the planks 10 near their forward edges by means of thebolts 13 and nuts 14. T preferably use two of said angle irons spacedapart from each other and arranged longitudinally in the machine, asshown in Fig. 1. Secured to the angle irons 11, preferably above thefirst and third planks, are upwardly extending brackets 15, arranged inpairs. Mounted in the brackets 15 are a pair of parallel runners 16,arranged transversely in the machine. The forward ends of the runners 16are beveled at 17.

Secured to the upwardly extending flanges of the angle irons 11 at theirrearward ends are rearwardly and downwardly extending brackets 18. Inthe brackets 18 is mounted a transversely arranged pipe or tube 19,whlch 1s fixed against rotation by means of bolts 20, extending throughsaid brackets and through said pipe, as shown in Fig. 2. For making thenarrow, parallel ridges 1n the ground hereinbefore referred to, a pluralty of harrow teeth are provided, each comprlsing a tooth portion 21 andan'upwardly extending shank portion 22 of smaller diameter than thetooth portion 21. The shank 22 is extended through suitable openlngs 1nthe pipe 19 and its upper end is screw threaded at 23, to receive a nut24:. The harrow teeth are inclined downwardly and slightly rearwardly,as illustrated in Fig. 2.

My improved pulverizer is preferably used with a weight 25 on the rearplank 10, whereby the teeth 21 are forced into the ground. As a matterof fact, the driver usually stands on the rearplank 10, therebyfurnishing the proper weight, but if desired, the weight 25 may be used.The weight 25 should be adjustable forwardly and rearwardly and alsolaterally for securing the proper action of the pulverizer.

The advantage of the use of a pulverizer such as that herein described,lies in the fact that the planks 10 thoroughly break up the dirt intofine particles and level the surface of the field. The smooth, levelsurface is then cut into narrow, parallel ridges of well broken up andwell cultivated dirt. The forming of the ground into ridges in manysections of the country puts it into the best condition for raising acrop. lVith ordinary drags and harrows, if there should be a rain afterthe'ground has been dragged, and left smooth, the soil is packed,leaving it in worse condition than before dragging.

With my improved pulverizer, the ground is smoothed and then left in thenarrow ridges and furrows, in which condition the furrows carry off thewater and the ridges are properly drained and dry. The soil is therebybetter aerated than when otherwise prepared and is left mellow andloose, without being baked by the sun after the rain. When the harrow isdragged from; place to place, it is simply turned overan d drawn wardlyand rearwardly, the flat members 7 along on the runners. 7 beingarranged in succession from front to 25 It will be understood that somechanges rear, with the forward end of each rearmay be made in myimproved pulverizer ward member overlapping the rearward end 5 withoutdeparting from its essential feaof each forward member, a pair oflongitutures and purposes and it is my intent to dinally arranged framemembers inclined cover by this application any such changes downwardlyand rearwardly at their rear- 30 which may be included within the scopeof ward iends, said frame members having my claims. right-angled flangesat their lower edges 10 I claim as my invention: to engage the flatmembers, bolts extended 1.
